Mine is faster since the update. Not that it was super slow or anything. Just that adding stuff to collections could take a few seconds each time as I have like 40 collections and 3000 or so cloud items.
. Now its almost instant adding stuff.
Like others said, check the indexing, might be a weird file? Restart might fix it all.
No issues on my Voyage. Batter does see to go down at tad faster. Hard to tell as I always have wifi on and I read a lot and use a lot of collections. I just assume all that will use some juice. I charge about every 2-4 days, more so every 3.
